TraitsUI is somewhere in between a graphical builder and writing source
code.  I've never used wxFormBuilder.  I started to use QtDesigner, and in
fact I was in the middle of figuring out QtDesigner when I discovered Traits
and TraitsUI.  I didn't learn QtDesigner well enough to comment in any

But I previously used Boa, and I can say with certainty that I find creating
a GUI with Traits and TraitsUI to be *much easier* than using Boa. And I was
never tempted to go back to QtDesigner.   On the other hand, I used to use
the Matlab GUI maker, and thought it was pretty easy to use.  That was many
years ago, now.     YMMV.    I'm a scientist, not a programmer.  I'm hooked
on Traits now.  Aside from the ease of GUI building, there is the whole
Traits way of doing things which very much helps me design my programs.   In
fact, you can see me quoted here:
